Unabla update ver3 via proxy

I have to update my Smart security via proxy. But after I set proxt setting and user name and password ( as I did in ver2.7.39 and could download update) , I can not download and bellow error appear. can you help me please?

As i have understood, this is Home version. So, I think, there shuould not work through various proxies. On Nov. 26, the business verison is expected which , on my opinion, will support update through proxy.
Is it like that, Eset Team?
